IMPROVEMENT IN HEATERS FOR PASSENGER-CARS.

Specication forming part of Letters Patent No. 34,280, dated January 28,1862.

' Improvements in Stoves or Furnaces for Heating Passenger'Railway-Cars, of which the following is a full, clear, and exactdescription,

reference being had to the accompanying drawings, making part of thisspecification, in Which- Figure 1 is a plan; Fig. 2, a vertical section.

My present invent-ion consists 1n an im` proved furnace or stove forheating passenger railway-cars, which I will proceed to describe in suchmanner that others may understand and use my invention.

In the said drawings, A represents the Hoor of the car, from the underside of which is suspended a furnace or stove B, an opening in the floorbeing commanded by a register C and perforated plate or grating D. Anouter casing E, which surrounds the furnace B, forms with a bottom platea an air-chamber F between it and the furnace. A series of openings b inthe bottom plate admit air to this chamber, which, after being heated bycontact with the Awalls of the furnace, passes up through the grating Dto the interior of the car.

The furnace has a circular grate G, pivoted on rods f, passing throughthe walls of the furnace and extending at one end through the outercasing E, Where it is operated by a handle g. An ash-pan H is hung belowthe grate, being hinged on one side to the bottom of the furnace.

The top of the furnace is formed, as shown in the drawings, with agutter h around the opening I, to receive sand 27, into which the lid leis set. Draft pipes .or` ues K open through the outer casing E-onetoward each end ofthe carwhich are commanded by dampers l, operated byrods m, which project up through slots o in the grating D. I have foundin practice a tendency of the gas and smoke from the burning fuel tocollect in the top of the furnace, so that when the lid k is removed forthe purpose of replenishing the fuel the gas escapes into the car. Toremedy this inconvenience, I have attached to each draft-pipe K anauxiliary pipe or iiue L, which makes a communication from thedraft-pipe to the upper'part of the furnace, by which the gas is carriedo.

The above-described furnace is particularly applicable to street-railwaycars, where the small amount of available space on the iioor does notadmit of the employment of an ordinary stove. For the purpose ofkindliug with more rapidity, or of heating up rapidly when the cars arestationary, the ash-pan may be slightly dropped, or it may be perforatedWith small holes to admit a portion of air from beneath.

What I claim as my invention, and desire to secure by Let-ters Patent,is

The furnace for railway aud street cars, constructed substantially asdescribed, with the fines K and auxiliary ues, said furnace beingarranged under the iioor of the car and operating in the mannersubstantially as set forth.
